     7  Set this flag to specify a remote repository that is used to store cache images. Buildah attempts to
     8  push newly built cache image to the remote repository.
     9  
    10  Note: Use the `--cache-from` option in order to use cache content in a remote repository.

    12  Example
    13  
    14  ```bash
    15  # populate a cache and also consult it
    16  buildah build -t test --layers --cache-to registry/myrepo/cache --cache-from registry/myrepo/cache .
    17  ```
    18  
    19  Note: `--cache-to` option is ignored unless `--layers` is specified.
